Beer Koozie's kick ass. Your beer stays colder for a longer period of time by keeping your body heat from killing the frosty chill that ones choice of beer has. I wouldn't go with that one because it isn't Burgundy and Gold but I guess i could make an exception in this case.

beer koozies are the epitome of a great invention. Keeps the beer cold and keeps my hand from getting cold and wet. It's a win-win.

They're also great for tailgating in late November or December when it's as cold as a witch's tit outside.
If you're working the grill or stuffing your face with brats you don't want gloves to get in the way. At the same time an ice cold aluminum touching your bare hand on a cold day isn't too much fun, so the koozie is literally saving your skin.
